2 Claims. (CI. 55-24) atthe top, permitting the feet to readily with-This invention relates to sheeps-foot rollers and particularly to theconstruction and form of the feet of such rollers, the presentapplication being a division of United States Patent No.

2,245,865, dated June 17, 1941.

The principal object of this invention is to provide tamping feet on theroller so formed that a very efficient ground compressingv or compacting'action is obtained, while at the same time the tendency for the feet totear out of the ground and loosen the adjacent portions of v the same ispractically eliminated.

The above object is accomplishedby means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims. i

In the drawing similar characters of referdraw from said holes Withoutmaterially disturbing the ground.

ence indicate corresponding parts in the several views:

Figure 1 is a side elevation of a sheeph-foot roller showing my improvedfeet mounted there- Figure 2 is an enlarged sectional elevation of afoot taken on the line 2-2 of Fig. 1.

Figure 3 is a top plan View of a foot.

Referring now more particularly to the characters of reference on thedrawing, the roller I is as usual supported in framing 2 and the feetare mounted on theroller in radiating relation thereto and in relativelyclose order. v

Each foot is a-hollow member formedof four plates 3. welded togetheralong their adjacent edges and arranged as the frustum of a relativelytall pyramid, which is capped by'a square and relatively heavy plate 4somewhat larger than the adjacent or outer end of the foot pyramid andwelded to plates 3 as indicated at 5.

The feet are weldedin place on the roller as relation so that thespacing between all the feet is substantiallythe same.

By thus constructing the feet they are large without being excessivelyheavy and their shape insures a compacting of the ground between the Inother words, the feet '3 from their inner ends to a point a substantialdistance outwardly therefrom'are of a cross sectional configurationsymmetrical to but larger than the cap plates (see Fig. 3), whichproducesupon penetration of the feet into the groundholes which at' andadjacent their top are substantially larger than but symmetrical to thecap plates so that the latter can withdraw from the ground with aminimum of disturbance thereof.

v Also, as the cap plates are relatively shallow radially of the feet,ground disturbance is further minimized.

From theforegoing description it will be seen that I have produced sucha device as substantially fulfills the objects of the invention as setforth herein.- 7

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as delined by the appended claims. 7

Havingrthus described my invention, what I claim as new and useful anddesire to secure by .Letters Patent is: i

l. A roller foot which includes an elongated outwardly tapering foot,and a cap plate secured on the outer end thereof; said cap plate in planbeing symmetrical to but larger than the cross sectional configurationof said outer end of thefoot, and the foot fromits inner end to a'pointa substantial distance outwardly thereof being of a cross sectionalconfiguration symmetrical to but larger than the cap plate in plan.

. indicated at 6 and are arranged in staggered 6 2. A roller foot whichincludes an elongated outwardly tapering foot, anda cap plate secured onthe outer end thereof; said cap plate being relatively shallow axiallyof and as'compared with the length of the foot and in plan beingsymmetrical to but'larger than the cross sectional configuration of saidouter end of the foot, and the foot from its inner end to a point asubstantial distance outwardly thereof being of a cross sectionalconfiguration symmetrical to butlarger than the cap plate in plan.
